Prognosis in Acute WAD

advertisement
Thesis project of Dave Walton PT, PhD(cand.)

To develop a new tool for use with acute WAD
patients that:
1. Is clinically feasible
2. Provides an estimate of the risk that a patient will
develop persistent WAD-related morbidity
3. Indicates the nature of the risk, focusing on
modifiable barriers to recovery, that will help in
clinical decision-making



2006 – 2007: Systematic review and metaanalysis of existing prognostic literature
(JOSPT Fall 2008)
2007: Construction of multi-dimensional
model for the development of chronic WAD
2007-2008: Development of the prototype
tool using the model as a framework for item
generation.




Items were generated by 5 physiotherapists
with experience in treating WAD (mean
clinical experience 12 years, range 8-18)
Well over 1000 items generated
Items reduced through group consensus and
theoretical considerations
Items passed by experts from other fields
(psychology, physiatry, questionnaire
development)

Tool now consists of two parts
1. 93-item self-report questionnaire
2. 19-item physical assessment
Self-report questionnaire reviewed and
edited by professional technical editor
Pilot testing:


◦
◦
Questionnaire: good acceptability so far,
average of 15-20 mins to complete
Physical ax: reliability testing currently
underway

Self-report questionnaire:
◦ Multiple sub-constructs hypothesized to predict
multiple outcomes within the spectrum of ‘WAD’





Symptoms
Coping strategies
Cognitions
Emotions
Past history

Physical assessment:
◦
◦

◦
◦
ROM (ordinal)
Peripheral key muscle strength (nominal)
Reaction to traction/compression (nominal)
Neck flexion in supine (ordinal)
Sensation (nominal)
Algometry (ratio)
Symptom reproduction (for each)

Recovery at 3 and 6 months post injury,
defined as:
◦ Not all bothered by symptoms over past week
◦ No interference with normal activities over the
past week
◦ Very satisfied with current situation
◦ No ongoing medication use for symptoms
◦ Return to full work or school (not included for
those unemployed or not in school)

Neck Disability Index (10 items)
Core Whiplash Outcome Measures (5 items)
Patient Health Questionnaire (9-item
depression screen)
PTSD Checklist (17-item PTSD screen)
Tampa Scale for Kinesiophobia (11-item
fear/avoidance screen)
Other individual items (bothersomeness,
ongoing litigation)
65 items in total at follow-up


Subjects who meet inclusion criteria are
presented with the LOI and consent form at
their first visit.
Those who consent:
◦ Name and contact info is recorded on a master list,
associated with an ID number
◦ Given the prototype self-report questionnaire to
complete within 24 hours

Completed forms are sealed in an envelope
and returned to clinic staff for storage



Standardized physical assessment is
completed after subjective interview but
before more targeted assessment techniques.
Findings are recorded and stored securely
with self-report questionnaire.
Master list must be stored in a locked cabinet
with consent forms at night
Completed forms must be stored in a
separate locked cabinet


After either a) 10 completed forms have been
collected OR b) once per month, completed
forms (not master list) are sent to Dave
Walton at UWO via Purolator (pre-paid).
Once per month master list is faxed to Dave’s
private fax machine.



At therapist’s discretion.
We are not trying to control anything to do
with intervention (good external validity,
some sacrifice of internal validity)
We will ask you to complete a checklist of the
general types of treatment provided, at either
D/C or 6 months, whichever is first. This can
be mailed or faxed.

Arranged by Dave and/or research assistant,
you don’t do anything regarding follow-up
for the study. The process will be (FYI only):
◦ We will either mail the forms to the patient’s house,
or email the patient a link to a secure site with the
forms online.
◦ Forms are completed and either mailed back to
Dave, or stored on secure server.
◦ This is done 3- and 6-months post-injury (approx.
15-20 minutes to complete)

Data!
◦ Clinics who see WAD patients post-MVA within 4
weeks of injury
◦ Clinicians who are willing to learn and perform the
standardized assessment on patients at their first
visit (pretty straightforward)
◦ Clinics with staff who are willing to:
 Screen potential subjects for inclusion criteria (w/i 4
weeks of injury, at least 18, able to read English)
 Provide the LOI, consent form and questionnaire
 Keep a master list and consent forms in a locked
cabinet
 Fax the master list to Dave once/month



530 total subjects
As many clinics as are interested
Ethics approval and data collection to start in
May ‘08





All the forms, including questionnaires, master
list with pre-generated ID numbers, envelopes.
Instructional manual and video for performing
physical assessment
A digital algometer and set of monofilaments for
sensory testing, for the clinic, as long as you act
as a data collection site
Recognition as a data collection site (certificate)
That warm fuzzy feeling that comes from
contributing to research in the field
